Sub-type polymorphism

WebWhen people talk about polymorphism in C++ they usually mean the thing of using a derived class through the base class pointer or reference, which is called subtype polymorphism.But they often forget that there are all kinds of other polymorphisms in C++, such as parametric polymorphism, ad-hoc polymorphism and coercion polymorphism.. These … Web20 Aug 2024 · The Inclusion polymorphism is called as subtyping. This allows to point derived classes using base class pointers and references. This is runtime polymorphism. We do not know type of the actual object until it is executing. We need virtual function in C++ to achieve this inclusion polymorphism. Example

In programming language theory, subtyping (also subtype polymorphism or inclusion polymorphism) is a form of type polymorphism in which a subtype is a datatype that is related to another datatype (the supertype) by some notion of substitutability, meaning that program elements, typically subroutines or … See more The notion of subtyping in programming languages dates back to the 1960s; it was introduced in Simula derivatives.
